6: Identify the true statement.
In deep-well pumps, you should check whether the pressure gauge is installed directly at the pump discharge.

6: Identify the true statement.
Online monitoring equipment does not check if a parameter has changed or exceeded a preset limit.
You can find the answer here >
6: Identify the true statement.
If all the parameters are recorded immediately after the pump has been installed, you can use them as benchmark against future data.
7: What causes cavitation?
Cavitation occurs when water changes its state from vapour to water at low pressure.
7: What causes cavitation?
Cavitation occurs when water boils at 100°C and changes its state from water to vapour at normal atmospheric pressure.
